Question 4 (10 marks) William has recently signed a 3 year contract with FNU as a Teaching Assistant. Under the terms of his employment, he works from Monday to Friday. William's new wife (who is not a good cook) offer's to cook and pack him his lunch for work. This will cost him an average of $1.98 per meal (For the purpose of the calculations, please round of the dollar ($$) value to 2 Decimal Places. This instruction holds for the rest of this paper). However, William has a bad habit of eating out and prefers to buy lunch on his work days at an average cost of $9.6400000000000006 per meal. Consider the scenario if William had chosen to deposit the savings into a bank account on a weekly basis. BSP is offering William a Savings Account package where he would need to make a weekly deposit of his savings. BSP would pay a nominal interest rate of 5.2000000000000002% compounded weekly. ANZ is offering a package where William would need to make a weekly deposit with a nominal interest rate of 6.5999999999999996% compounded annually. a.)
